Category:CS1 maint: unrecognized language

It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. They are not part of the encyclopedia's categorization scheme.

These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.

These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.

This is a tracking category for CS1 citations that use |language= where the assigned value is not recognized by MediaWiki. MediaWiki recognizes all of the ISO 639-1 two-character codes and some of the ISO 639-2 three-character codes, along with the full official names of the languages corresponding to those codes. See the list of supported codes / names.

MediaWiki is particular about language name spelling. For example, Northern Sámi should be spelled Northern Sami. MediaWiki does not recognize three-character codes when there is an equivalent two-character code: for Northern Sami, use code se instead of code sme. For recognized ISO 639-2 languages with multiple official names, MediaWiki recognizes only one. For example, code crh can refer to Crimean Tatar or Crimean Turkish; MediaWiki recognizes the latter.

Text that is not a recognized language code or name (the 'and' in |language=German and French) will add the article to this category because the citation module is looking for a single language name or code, or a comma-separated list of language names and/or codes; |language=German and French should be changed to: |language=German, French.

Even with this css installed, older pages in Wikipedia's cache may not have been updated to show these error messages even though the page is listed in one of the tracking categories. A null edit will resolve that issue.
